ABSTRACT
Objective:
The present study aims to develop a histolo-gical descriptive analysis on the repair of bone defects filled with ?-TCP, associated to pure titanium implants into cavities prepared in the calvarial bone of rats. Ma-terials andmethod:
Eighteen male adult rats were ran-domly selected and divided into three groups of six rats each, according to their period of death 15, 30, and 60 days. Four bone defects were made into each one of the calvarial bones of rats and filled with (a) ?-TCP, (b) clot, (c) ?-TCP + pure titanium screw, and (d) pure titanium screw. The samples were cut and histologically assessed. Presence and volume of loose connective tis-sue and newly formed bone tissue were analyzed, as well as the presence or absence of remaining material (?-TCP) into the defect.Results:
It was verified an acce-leration bone neoformation process in the presence of ?-TCP.Conclusion:
The results suggest the biocompa-tibility and osteoconductivity of the biomaterial, even when associated to pure titanium implants.
